Keep the soil consistently moist but not waterlogged. Water thoroughly when the top 2-3 cm of soil feels dry. Reduce watering frequency during the cooler, dormant periods to prevent root rot.

Ensure good drainage to avoid standing water.

Prune to maintain desired shape and size, and to remove any dead, damaged, or crossing branches.

Light pruning can be done anytime, but heavier pruning is best done in late winter or early spring before new growth begins. Use clean, sharp tools.

Propagate from semi-hardwood cuttings taken in late spring or early summer. Dip the cut end in rooting hormone and plant in a well-draining potting mix. Maintain high humidity and warmth to encourage root formation.

Seed propagation is also possible but slower.

Repot your Psychotria carthagenensis every 2-3 years, or when it becomes root-bound. Choose a pot one size larger with fresh, well-draining potting mix. The best time to repot is in spring, just as new growth begins.

Handle the roots gently.
